The methyl ester of nicotinic acid
Well, the free acid, and its amide form, are better known as Niacin, a vitamin.
What you have is pyridine 3-carboxylic acid methyl ester.
I am unfamiliar with any particular applications for this ester.
Nicotinamide you can dehydrate to the nitrile or you can oxidize the pyridine ring to the pyridine-N-oxide but those are five-finger exercises from
Org.Syn. as well and AFAIK don't really lead anywhere very interesting.
Why don't you google "methyl nicotinate" and see what pops out?

The quartenization product that arizes by MeI treatment can be reduced wityh NaBH4 to yield an alkaloid with quasi-stimulant psychoeffect (arecoline).
It is also produced during the course of the metabolism of betel nut. it is an easy synth needless to say...

is MeI treatment is nessesary, nor-arecoline will be react with Grinhard 4-ClPhMgBr or PhMgBr (-20C needed to produce "right" isomer) and then
halogenation, for example with Br2 in AcOH?

Get a book on basic organic chemistry, go to the chapter on Amines, find the section on Quaternization of Amines or Quaternary Ammonium compounds and
start reading.
Also UTFSE, which in case you don't know, stands for Use the Frigging Search Engine.
Google is also a good idea in the same regard.

ok thank's for the moment, i find a patent for making arecoline but the yield is not very good (about 43%) if you know a better idea with higer yield
pleas tell me

so i need a good method for methylation of methyl nicotinate (the NH group) , with CH3J is a good idea? and
the parameters? (pressure, temperature etc.) a better idea of metylation? thanks

check this patent US 6132286. (55% after reduction NaBH4).
what you want to do? arecoline?

from arecoline you can synt antidepresant nocaine (UTFSE).

You asked about methylating the NH group in methyl nicotinate
There is no NH group in methyl nicotinate
There is the N in the pyridine ring only. You can't methylate it, it is tertiary (aromatic) but you can quaternize it.
Is that what you mean?
Or do you want to reduce the pyridine ring and end up with methyl nipecotate? That has a -NH group and can be methylated (perhaps with some
difficulty).
You see, your post was imprecise and ambiguous, which makes a meaningful reply difficult.
